A recent study published in the Journal of the American Geriatrics Society indicates that individuals with anxiety disorders may face a significantly higher risk of developing dementia later in life, potentially tripling their chances compared to those without such disorders.
Dr. Kay Khaing, the lead author and a specialist geriatrician at Hunter New England Health in Newcastle, Australia, highlighted that anxiety should now be recognized as a non-traditional risk factor for dementia. This study is notable for its exploration of how varying severities and durations of anxiety influence dementia risk over time.
The research, conducted among 2,132 participants aged 60 to 81 from the Hunter Community Study, spanned over a decade with assessments every five years. It identified chronic anxiety (present at multiple assessments) and new-onset anxiety (developing during the study) as key factors associated with nearly tripling the risk of dementia. Conversely, anxiety that resolved within the first five years showed no significant increase in dementia risk.
The study underscores the importance of early and consistent management of anxiety, not only for mental health but potentially for reducing long-term risks such as dementia. Dr. Joel Salinas, a neurologist not involved in the research, emphasized the need to address anxiety promptly, citing its detrimental effects on brain health and its association with conditions like Alzheimer’s disease.
While the study suggests a strong correlation between anxiety and dementia, experts caution that further research is needed to explore underlying mechanisms and potential interventions. Managing anxiety through lifestyle changes, therapy, and avoiding certain medications that may impair brain function are recommended strategies.
This study adds to growing evidence linking mental health conditions with long-term cognitive health outcomes, highlighting the importance of proactive mental health care across the lifespan.
